Her Comic Relief challenge did not get off to a good start on Monday when she was injured before things even began.

So it's no wonder that Miranda Hart was left aghast when she was told what she must do as part of her fundraising attempt on Tuesday.

The statuesque comedienne, who required hospital treatment after falling over on her heels and injuring her knee after arriving in Newcastle, has now been given the task of learning a Dirty Dancing routine to perform at a Strictly Come Dancing theme night - which will be broadcast live on The One Show on Tuesday afternoon.

Working hard: Miranda Hart has been given the task of learning the iconic Dirty Dancing routine for the latest step in her Comic Relief challenge

This'll be you in six hours! Miranda is learning the routine, as well as the famous lift, from Pacha Kovalev and Katya Virshilas

In picture from the practice session posted on Twitter by Red Nose Day, Miranda is seen attempting to push through the pain by wearing a knee brace as she rehearses with Strictly professional Pacha Kovalev and dancer Katya Virshilas.

The shot was captioned: 'The knee is just about holding up during what is a hectic practice session Lot to learn & remember #mirandasmarch.'

After discovering the nature of Tuesday's challenge, Miranda tweeted: 'Waxing armpits with a bad knee is one thing but DANCING! Next challenge - perform at and organise Strictly theme night. Be live on One show.'

And speaking to Ken Bruce on BBC Radio 2 on Tuesday morning, Miranda said: 'I’m not quite sure how I’m going to dance - there’s going to be hobbling and standing still. Katya said just stand still and look sexy, I said I’ve never done that in my life!

Moral support: Miranda was joined at the rehearsals by her former comedy show co-star Sarah Hadland

I'm trying! It remains to be seen whether or not injured Miranda will be able to complete the lift

'People have been amazing in texting in and raising money already, I’m going to do whatever it takes. I’ll do that "come hither" look, that’s the look to go for I think. Donate if you possibly can, I’ll love you forever. Now, I must get my dancing shoes on!'

And asked on BBC Breakfast whether performing the Time Of My Life routine might be some women's idea of heaven, Miranda replied: 'It is, if you haven't only just been able to stand up after 36 hours.'

The funnywoman was left in agony ahead of her first stunt for Miranda's Mad March when she fell over while wearing her heels.

The injury ate into her practising time for a world record attempt on live TV on Monday night - to wax the armpits of burly rugby players - which she failed...

I can't believe you're here! Miranda giggles with delight as she realises Sarah has arrived to give her a helping hand

Hugs all round: The pair, who starred together in Miranda, looked thrilled to see each other

Speaking to Chris Evans on Radio 2 the morning after her accident, the star admitted: 'I should have known better, I was wearing a heel at the time, which is ridiculous as I’m 6ft 1in.'

'To be honest, it was only an inch and a half heel but that was enough to do it, I normally only wear ballet pumps,' she said.

'I was in my hotel room and it just went. So much for my Mad March - this is now definitely going to be Miranda’s Mad Hop,' Miranda added.
